Setup of the development environment
Prepare for developing for the IntelliJ AsciiDoc plugin.
Choosing a Java Version and Distribution
Starting with IntelliJ 2020.3 and plugin version 0.32.x, JDK 11 is required to build the plugin. See the JDK 11 announcement in the JetBrains blog for details.
As the 0.32.x releases support also IntelliJ 2020.2.x, programming is restricted to use only Java 8 functionality, so that the plugin runs on both JDK 8 and JDK 11.
JetBrains recommends Amazon Corretto JDK for development, but other distributions based on OpenJDK should work as well.
For the Gradle build tool to pick up the Java version, point the environment variable JAVA_HOME to the folder with the JDK:
Setting the environment variable on Linux/MacOS
export JAVA_HOME=...
Setting the environment variable on Windows
JAVA_HOME=c:\workspace\...
Verify your environment
You can check your environment using the following command in the root folder of the project:
Linux/MacOS command
./gradlew --version
Windows command
gradlew --version
The output should be similar to:
------------------------------------------------------------ Gradle ... ------------------------------------------------------------ Build time: ... Revision: ... Kotlin: ... Groovy: ... Ant: ... JVM: 11.0.x (Amazon.com Inc. 11.0....) OS: ...
